From 19e1b8d9b283514eb6ab8d7253f4867068007938 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Fri, 16 Apr 2021 14:53:46 -0700 Subject: [PATCH] pci: Update the highest subordinate bus number for bridge setup Update the highest subordinate bus number after probing the devices under the bus for setting up the bridge correctly. The commit 42f3663a3f67 ("pci: Update to use new sequence numbers") removed this but it is required if a PCIe bridge is under the bus.
